Value Collection DA.5X03.0X36 4140 Steel Flat Bar

Product Description

The VALUE COLLECTION DA.5X03.0X36 is a 4140 alloy steel flat bar supplied in a pre-hardened condition, ready for use in tooling, fixturing, die components, and general machine-shop applications. Measuring 0.5 inches thick by 3 inches wide by 36 inches long, this bar arrives with elevated hardness already achieved through the mill heat-treatment process, eliminating the need for additional hardening before use. At 16.64 pounds per bar, it offers substantial mass suitable for moderate to heavy fabrication tasks. Machinists, tool-and-die makers, and maintenance technicians working in industrial and manufacturing environments are the primary installers and end users of this material.

4140 pre-hardened alloy steel flat bar is commonly used in jig and fixture construction, wear plates, die shoes, shafts, and structural machine components where a combination of toughness, strength, and machinability is required. The 36-inch length provides sufficient stock for multiple smaller parts to be cut from a single bar, making it a practical choice for job-shop and in-house maintenance operations. This bar is suited for both manual and CNC machining environments.

Key Features

• 4140 alloy steel composition for high strength and toughness
• Pre-hardened condition eliminates post-purchase heat treatment
• 0.5 inch thickness by 3 inch width flat bar profile
• 36-inch length yields multiple part blanks from a single piece
• UNSPSC Code 30263600 for procurement and classification systems

Compatibility

Designed as a general-purpose 4140 pre-hardened alloy steel flat bar suitable for tooling, fixturing, die-making, and structural machine component applications across industrial and manufacturing settings.

Installation Notes

Cutting, drilling, and milling of 4140 pre-hardened steel should be performed by qualified machinists using appropriate carbide or high-speed steel tooling rated for hardened material. Secure the bar firmly in a vise or fixture before any machining or cutting operations. Welding pre-hardened 4140 requires pre-heat and post-weld heat treatment procedures in accordance with applicable industry standards to avoid cracking. Always use appropriate personal protective equipment when cutting or grinding this material.
